The jig model I created myself, but I used the little ‘wing’ inserts from evanfort's 216 jig, so you will need to grab those and print them as well. Main difference is mine has center lineup marks and screw holes vs the edge guide in evanfort's jig.

I didn't have the trim router with evanfort's suggested base, so I took inspiration from rothnic's trim router insert and modeled one up that works with a Makita RP1800 plunge router.
